How is a thickness planing machine structured?
The thickness planer consists of several parts different functions, Although there are different models, good thicknesser are constructed as follows:
- standing enclosure
- Feed and extract roller
- check gripper
- table rollers
- pressure beam
- planer blades
- handwheel
- suction
The stand housing consists of several hinged parts. They serve partly as a cover and for fixing other components.
The carriage of the workpiece takes over the feed and the extract roller. This is done by the contact pressure.
The blowback grapple turn, ensures that the wood does not hit back on adhesions or bumps. It is a kind of folding bracket, which is located on the feed roller.
The table roller or rollers on the machine table ensure that the workpiece can slide through more easily. The number of rollers can vary.
Pressure beam ensure that the workpiece is pressed on the knife table and prevent vertical movements thereof.
The planer knives on the planer knife shaft are responsible for the chip removal. A good thicknesser can own 1, 2 or 4 planer knives. These rotate opposite to the workpiece feed at different speeds, which is the reason for planing off.
The desired thickness can be set with the handwheel , the best thickness planing machines have an electric servomotor for this purpose.
suction, a professional thicknesser is always equipped with a suction device, which removes the chips from the planer shaft by means of negative pressure. A cheap planing machine often only has a suction nozzle for connection to a vacuum cleaner.
For those who like to work with wood, a professional model is just like that Güde Thicknesser, our comparative test winner, the non-plus ultra in woodworking. Therefore, pay attention to the range of functions and whether tilers and thicknessers should be anchored in a machine.
